calculating load loss using fork extensions
calculating load loss using fork extensions
(OP)
I'm trying to find a way to calculate the max load a fork lift can handle if you are using fork extensions, for example I have a lift rated at 5400 lbs at 24 in load center. How would I figure max capacity at 36 in load center. Reason I am asking is I have a gear box that I have to remove and will have to use 6 ft extensions to be able to get to it. Gearbox weighs 680 lbs. Don't need anyone to calculate it just steer me in the direction of a formula or where I could find one. I'll do the math. Personally I think I am well within the safety "bounds" of the equipment.

But their answer **MAY** go something like this:
(allowable bending moment on the stock fork) = (5400 lbf) X (24 inches) = 129,600 lbf-in
(AND it should be higher than that due to an unknown Safety Factor.)
Do the substitution for 36 inches, then
(allowable load @ 36") = 3600 lbf
Anybody else have a more accurate approach?

It's basically the ratio of the load centers, but the manufacturer may also consider the effect of the weight of the fork extensions if you asked them for a number. Doesn't look like you need to worry about it though based on your numbers.

Here is what we used for extended reach lifting with fork trucks.
